Boarding was civilised and we found our seats in row 12 which is actually row 2. For some reason they start the row numbers from 11 upwards
This is standard practice with Thai: Row 1-10 is F, 11-30 is C and from 31 and up is Y. Even if they don't have F on the plane they still start counting from 11.
To some it's weird. To others it make great sense. As long as you know it, it's no big deal.
